Temporary Internet Files\Content.IE5 folders

Cleaning up a computer today I was looking at the Temporary Internet Files\Content.IE5 folders There were about 8 folders there with random numeral and letter names.
I found many .jpgs there that were of no use like Lucious Lacy, etc.

After I ran CCleaner that took awhile I noticed that each one of these folders were empty of stuff except for one icon.

There were also less folders than 8 now.

Does Windows make these content folder as it needs them and leaves a certain number left for future use?

If it needs more it makes them?

If I wanted to delete the contents of each folder manually except for this one icon is this OK?

What about the extra folders?

Is there a default number of folders that Windows XP keeps there?

It probably varies by how many days you tell the web browser to keep items in memory.
It may also vary depending on how much memory you tell the browser to use for cache.
I personally set my browser to 0 days in memory and a very low cache size. It is safe to
delete them, as the browser will recreate as needed

Delete what?
1. The random folders that look like this: R445TGK
2. The content of those folders
3. The Content folder
4. The IE5 folder

You can delete the folders with the random names.
Almost anything in C:\Docs & Settings\User Name\Local Settings\Temp
cab be safely deleted. Do not delete anything under Local Settings\Application Data
